LARD-LAMP.

Specification of Letters Patent No. 15,864, dated July 15, 1856.

T 0 aZZ whom it may concern:

Be it known that I, JEREMIAH S. SENSENY, of the borough of Chambersburg,in the county of Franklin and State of Pennsyl- Vania, have invented anew and Improved Lard-Lamp; and I do hereby declare that the followingis a full and exact description thereof, reference being had to theaccompanying drawings and to the letters of reference marked thereof.

a is the lid Z) the top to which the lid is attached; 0, is thefountain-head, to receive the cold lard and tallow, or oil; (l is thestand on which the fountain rests; e is the bottom of the lamp; f is thelower and g the uper joint of the burner; 7b is the slide containing thewick, extending to the bottom of the burner; 2' is the copper wireheater, extending into the fountain; j is a spigot, uniting the fountainwith the burner; 76, is a screw inserted in the spigot, rendering itair-tight, and by which the lard, tallow or oil is supplied to or cutoff from the burner; Z is the handle of the lamp, and m is the bottom ofthe fountain.

In the operation of my invention the lamp having been constructed asdescribed, the lard, tallow, or oil is first heated to a liquid state,the lamp is for the first time filled by lifting the top and pouring thefluid into the reservoir, and the spigot is turned to let the fluid flowinto the burner Z, and by means of it the flow can be regulatedaccording to the quantity consumed. After the lamp is filled by thefluid lard or oil, it can be refilled at any time without liquefying thelard or oil, which is a great saving in time, and expense in the summer,as there will be no need of kindling a fire for the purpose of heatingthe fluid before the lamp is refilled. As I can feed my lamp with thelard or oil in a hard state, I thus am enabled to construct a lampself-feeding and heating capable of being filled by lard or tallow in ahard state, which has not yet been done to my knowledge. I also make anew article of manufacture hitherto not brought into the market.

I do not claim a selfheating lamp simply, as this has been done by C.IVilhelm in his patent of April 6th 1842, and by J. Smith and J.Stonecifer in their patent of August 8th 1854. Nor do I claim simply theuse of a spigot for regulating a flow of the material to the lamp asthis is done by C. 1Llieidhof, in his patent of July 27th, 1852,

What I do claim is:

The arrangement and construction of a lamp as herein described, and forthe purposes set forth.

JEREMIAH S. SENSENY.
